Definitions

  • the invention relates to a weir flap which is pivotable about a horizontal axis of rotation arranged near its upper edge above a stationary overflow threshold, with its lower edge in a closed position and is loaded by a counterweight arranged at the downstream side from its axis of rotation, which counterweight is opposite the upstream side provides the required closing or throttling force.
  • rain overflow structures are provided in mixed water sewers that relieve the sewer network and a sewage treatment plant connected to it, in that part of the mixed water flows into a receiving water and the sewage treatment plant is fed only the mixed water quantity corresponding to its processing capacity from a dirt storage or rain overflow basin.
  • the overflow openings associated with such reservoirs have a large height in order to keep a sufficient discharge cross-section available for the water which continues to flow in the event of continued maximum loading of the sewer network above the overflow threshold.
  • the additional height of the pool above the overflow threshold Moving weirs are increasingly being used to use storage volume.
  • the drainage of dirty water can be throttled or the critical mixed water outflow can be dammed up so that an additional storage space is created in the channel section in front of the overflow or in the pool. If the weir flap is stored in the area of its upper end, it automatically prevents the floating contaminants from flowing into the receiving water when it is opened. In addition, with a swiveling weir flap, reliable backwater protection against flooding in the receiving water can be achieved.
  • the invention has for its object to improve an underflow weir flap of the type mentioned and its adjustment mechanism such that in addition to a simple inexpensive construction, a very small accumulation level fluctuation is achieved, i.e. the difference between the accumulation height at the time the flap is opened (the discharge to the receiving water begins) and the maximum accumulation height, which can be adjusted or maintained with any inflow into the basin using the opening adjustment of the flap.
  • the profile of the weir flap between the sealing edge and the axis of rotation has an arch shape at least over a section, preferably with an arch that is outwardly or convexly curved toward the downstream side, the dynamic water forces are better transmitted to the axis of rotation, in particular when the weir flap is in a larger opening position, in order to allow moments to take effect there which are similar or equal to the moment generated by the counterweight during the flap pivoting.
  • the axis of rotation of the flap can be arranged at 2/3 of the vertical height between the upper edge of the overflow threshold and the accumulation target, thereby achieving that the flap has closing forces due to the effective accumulation height above its axis of rotation and the counterweight or closing weight can thus be made smaller.
  • the axis of rotation of the flap can be arranged at 2/3 of the vertical height between the upper edge of the overflow threshold and the accumulation target, thereby achieving that the flap has closing forces due to the effective accumulation height above its axis of rotation and the counterweight or closing weight can thus be made smaller.
  • Claim 9 proposes that in each open position of the weir flap a counter torque matched to the water pressure forces can be achieved by adjusting means on the lever arm of the counterweight, which move a displacement of the suspension point of the counterweight during the locking process by deflections between the counterweight and its suspension or application point on the lever arm . These measures are useful, for example, if the axis of rotation is mounted very close to the ceiling of the drainage channel to save space and if the lever arm in the closed position of the weir flap is inclined downwards instead of the usual horizontal path.
  • the suspension point for the counterweight can be provided in a sleeve or a sliding block, which is automatically movable or displaceable in a possibly elongated slot slot of the lever arm when the lever arm reaches a certain upward inclination, so that in the case of a weir flap with straight profile the counterweight moment is automatically reduced when the water pressure forces acting on it decrease when the flap is wide open.
  • an overflow structure for example a storage basin, is shown in the form of a vertical wall 10 with a transverse discharge opening 12 arranged therein at a certain height, the underside of which extends with it their larger length perpendicular to the plane of the rectangle opening forms an overflow threshold 14.
  • the vertical wall 10 can consist of a side wall section of an overflow basin 16 or an inlet channel, for example, opening into this tangentially. Downstream or to the right of the vertical wall 10, the drain opening 12 opens into a relief channel 18 leading to the receiving water.
  • the maximum fill level of the overflow basin 16, which is normally determined by the overflow threshold 14, is increased by throttling the mixed water outflow by means of a weir flap 20 according to the invention to a desired accumulation target with a maximum accumulation level 24.
  • the weir flap 20, which extends at least across the width of the relief opening 12 and is guided on both sides by means of seals (not shown) on associated lateral sealing surfaces / guide walls of the drainage channel, is firmly connected in the region of its upper edge to an axis of rotation 22, which is preferably at the level of the storage target or is slightly above or below it.
  • the profile of the weir flap 20 has a course 26 which is curved convexly towards the underflow side between its lower edge, which lies against the overflow wall by means of a seal 30, and the lower half height dimension of the flap has the arc shape and the upper half height dimension 28 can run straight. It is essential in this weir flap that it is inclined downstream from the lower edge in the closed position shown with solid lines, namely at an acute angle W between about 20 ° to 60 ° with respect an imaginary vertical line starting from the lower attachment point.
  • the weir flap between the lower sealing edge and the axis of rotation can also have a straight course, as indicated by the straight line G, which extends in the closed position of the flap between the lower edge 30 and the axis of rotation 22, an arched profile shape is preferred because there the water flowing out into the
  • the torque curve generated in various opening positions of the flap on an essential area of the flap adjustment path is approximately the same as the curve of the restoring moments generated by the counterweight. Due to this torque adjustment, which is largely available over a substantial adjustment range, the jam level fluctuations that occur due to the control action of the flap can be very low, e.g. be kept in the range between 1 and 2 cm.
  • the upper end of the weir flap 20 as well as one (or more) lever arm (s) 38 of suitable length are attached to the axis of rotation 22, which is supported in tabs 32 projecting downward from the building ceiling 44, which has a suspension point 40 at its free end for a counterweight 42, for example in the form of an opening in which one (or more divided) counterweight (s) is (are) suspended by means of a rope or a handlebar.
  • the direction of extension of the lever arm 38 is selected so that in the side view a straight connecting line between the suspension point 40 of the counterweight and the axis of rotation 22 corresponds to the horizontal (when the flap is closed) in the example shown, the congestion target congestion mirror 24) form an angle in the range from -20 ° to + 20 °.
  • One or more stiffening struts 46 can be provided between each lever arm 38 and the stiffened rear side (underflow side) of the weir flap 20.
  • a free end 36 of the weir flap 20 which extends above the axis of rotation 22, bears against a horizontal seal of an apron 34 which is guided vertically downward from the building ceiling. This top seal is used when it is a "blocked" weir flap or in the case of a high backwater backflow a complete drain towards the upstream side is necessary.
